I wanted to build a modern version of the Dynaco ST70. Take the original circuit and improve with a better driver board, more filtration, better parts and cleaner layout. Well, this is what I came up with. The only original parts are the output transformers.

Terrific! How does it sound and what speakers do you use it with?

Patience my son. Good things come to those who wait. This is my latest project and still under construction. Here is a progress pic.
